Description

跟部带弹性镶嵌件的运动鞋
本发明涉及一种运动鞋，这种鞋由鞋面和下支承部分构成，下支承部分则由鞋底和装在鞋底上的楔形件构成，在楔形件内装有相互叠置的衬垫和内底，内底与穿鞋人或穿鞋运动员的脚部接触。
多年来，人们要求运动鞋在使用中能使穿鞋人动作时传到地面上的能量中有一部分以推力的形式返回给穿鞋人，这有利于抬足并使动作容易些。
对这种运动鞋的特殊要求是：
(1)实际上能全部消除穿鞋人，特别是运动员，在跑动中由跳跃动作引起的冲击力，从而保护其骨状组织和关节组织。
(2)在穿鞋人踩在鞋上时能使其脚部处于最佳状态，从而防止骨状组织受到任何变形。
(3)能矫正穿鞋人下肢旋前和旋后的缺陷。
目前已有各种谋求满足上述要求的结构，举例来说，其中之一在鞋的下支承部分内设有气垫，其尺寸基本上等于楔形件的尺寸，即：气垫沿整个脚部长度设置。另一种结构在其整个内底的下表面上具有向楔形件凸出的一些构件，再一种结构则在鞋跟部位具有蜂窝构件。
所有这些结构都具有不容忽视的缺点，例如，制作装有气垫的鞋费用很高，而又不能完全满足以上所述要求，这样，尽管可通过沿整个脚部长度设置气垫来取得相当舒服的鞋，然而这种鞋并不能产生要求作用在脚上的推力。而且，这种气垫不能使鞋具有多向稳定性和柔性。
尽管上述鞋的其他结构使穿鞋人脚部感到舒适，但不能合理地达到以上所述目的。鞋的其他结构至少能部分地满足以上所述要求，但其价格过高以致使许多纯属一般爱好散步的用鞋人不敢问津。
因此，本发明的目的在于提供能满足以上所述要求的运动鞋，更为突出的是这种鞋能将穿鞋人传给地面的压力传回到穿鞋人的脚上。本发明的另一目的是使所提供的运动鞋不会影响穿鞋人向鞋的前部施加压力，而且还具有多向稳定性和柔性。
这些目的以及对一般的专业人员来说比较明显的目的可通过以上所述那种运动鞋来达到，这种鞋的特征是：至少具有一个与下支承部分关联的镶嵌件，镶嵌件为受压弹性变形件，最好装在塑料的气密外套内，此镶嵌件装在楔形件和衬垫之间，并位于脚跟部位的座内。
座最好设置在楔形件内，并用叠置在其上面的衬垫盖住。
通过以下对附图所作详细的说明可对本发明及其优点了解得更为全面。
图1为本发明运动鞋下支承部分的部件分解图；
图2为本发明运动鞋的底视图；
图3为图2中III-III剖面图；
图4为另一实施例的剖面图。
参照附图，本发明的运动鞋由鞋面A和下支承部分1构成；下支承部分1具有鞋底2(例如用合成橡胶制成)，在鞋底2上用已知方法固定有楔形件3(例如用热塑性聚氨酯制成)。楔形件3有一凹部4，在凹部4周围有凸边10，楔形件内装有衬垫5(例如用软木制成)，在衬垫5上有内底6(例如用织品制成，图3上未示出)。鞋底2(最好用橡胶制成)在其下表面上有普通的凹口7和凹槽8，鞋底2上还有前凸边11和侧凸边12，侧面边12位于鞋底除前凸边外的整个周边上。
按本发明，在鞋的下支承部分1内有镶嵌件13，镶嵌件13由一些用热塑性材料制成的可变形的弹性件14构成，弹性件14封装在用聚氨酯或类似材料制成的气密外套15内。在外套15内有空气，其压力低于或等于大气压。在此实例中镶嵌件13位于座16和17内，座16和17分别位于楔形件3和衬垫5内，彼此叠置。
座17可以省去，而使镶嵌件13仅置于楔形件3的座16内，而将衬垫5置于座16上面。
更具体地说，镶嵌件13的弹性件14是用高弹性合成材料模制而成的，大体上为桶形，即在其彼此相对的自由端18和19处的锥形，其较大的横截面位于中心区20，这些弹性件在中心区20由连接部分20A连接在一起。根据镶嵌件13在制造上的要求将桶形弹性件14的自由端18、19固定在外套15上。这实际上是镶嵌件13的一个最佳实施例，也就是，首先模制弹性件14，然后将其装在用塑料薄片热焊成的外套15内；将弹性件14在较高的温态下就封装在薄片内，以便将其自由端18、19与薄片焊接在一起。外套15与桶形弹性件14的连接具有使弹性件固定在外套内的优点。从而按本发明可防止在穿用此鞋时外套和桶形弹性件的移动，并通过桶形弹性件14的相互连接使鞋具有良好的多向稳定性和柔性。这为鞋内的镶嵌件13提供较大的稳定性并可取得预期的良好功能。对于这些功能下面将予以进一步说明。
作为实例，图示和所述弹性件14的形状可以大量吸收人脚活动时所产生的应力，同时还可将大部分吸收的能量快速而平稳地传递到脚上。
为使镶嵌件13固定在座16和17内，在内底6面对衬垫5的面21上有一与座形相应的凸块22，使凸块22与座和镶嵌件13协同动作。在上述的另一实施例中，凸块22可以省去。
镶嵌件13的外套15具有一凸缘23，将镶嵌件13置于鞋的下支承部分1内时，凸缘23即置于衬垫5和楔形件3内表面25之间的台阶24上。也可省去孔或座17，此时凸缘23(很薄)即置于楔形件座16的周边上。
最后，在镶嵌件13的下面或在鞋底的其他可能设有另外的镶嵌件的部位具有加强件28，加强件28(例如用弹性材料制成，即用天然橡胶或合成橡胶制成)最好有些透明，加强件28可着色可不着色。加强件28用耐磨材料制成，至好设于鞋底的后跟和跖骨部位。
根据本发明，用鞋时，穿鞋人的脚每向鞋的下支承部分加压一次，就将镶嵌件13压向鞋底2。特别是，脚所施加的压力作用使弹性件14压缩变形并使气密外套15内的压力增大，因为气密外套15受到其座周壁的阻挡。当穿鞋人停止其后跟的加压作用时，弹性件14即恢复其原有形状。从而将施压时所取得的大部分能量传递到穿鞋人的脚上，因此，当其脚跟(或脚的其他部位，如跖骨)离开地面时，脚部就得到平稳的推力。在弹性件14施加在穿鞋人脚部的推力上还必须加上镶嵌件13内部空气所施加的推力，这部分空气是由于穿鞋人脚部的动作而处于受压状态的。这种组合的推力促使穿鞋人运动时传给地面的能量部分地又传到穿鞋人的脚上。
上述弹性镶嵌件也可置于下支承部分1的其他部位，具体地说可以置于鞋底2和楔形件3的前区附近。这样就可使穿鞋人(特别是运动员)在加速或改变其运动速度时取得更大的加速性能。
图1和图3所示镶嵌件13只有一层弹性件14，但是，可以设置如图4所示具有两层或多层叠置弹性件14的镶散件13。特别是，如果上述镶嵌件具有两层弹性件14时，第一层支承第二层，第二层的变形弹性件则置于下层弹性件之上。
这使部分的能量(穿鞋人传到地面上的能量)返回到穿鞋人脚上的状况得到进一步的改进。必须注意的是：与上述情况相同。桶形弹性件14的自由端18、19是固定(或焊接)在外套15上的，在采用两层弹性件14的情况下，此两层弹性件14的接触面就应相互固定(或焊接)起来。这可使镶嵌件13具有稳定性，防止外套15内层与层之间的滑动。根据本发明制成的鞋可以满足以上所述要求，特别可使运动时消耗的能量绝大部分重新传回到脚上。
很明显，在以上论述的基础上，可以对本发明作出多种修改和变更。
由此可见，在所附各项权利要求的范围内，本发明可用与本说明所述不同的方式来实施；特别是，除位于楔形件3后跟区内的镶嵌件13外，本发明可采用另外一些位于所述楔形件适当部位(如弓形区)的镶嵌件，此镶嵌件类似于镶嵌件13。
